Abstract

Application of Virtual Reality (VR) has attracted many researchers in computer simulation fields. In this paper, an improved mass-spring model is proposed aiming at realistic simulation of tissue deformation. Firstly, virtual springs are proposed to represent the surface. Secondly, Verlet integration is applied to calculate the position of mass points during deformation without explicit computation of their velocities. Finally, a bilinear interpolation method is employed to generate a smooth mesh to render the deformed surface. The proposed method has been implemented using OpenGL which generates realistic deformation images in real-time.
